Carmen Lúcia Ruby
Photography by Chip Clark. Gift of Dr. Peter Buck in memory of his wife, Carmen LĂșcia Buck, 2004.

At 23.10cts, the Carmen Lúcia Ruby is the largest faceted ruby in the National Gem Collection and one of the finest large, faceted Burmese rubies known. This natural ruby possesses a combination of outstanding characteristics. Aside from its large size, this extraordinary gemstone displays a richly saturated homogenous red color, combined with an exceptional degree of transparency. The stone was mined from the fabled Mogok region of Burma in the 1930s. While sapphire, emerald, and diamond gems weighing hundreds of carats exist, high-quality Burmese rubies larger than 20 carats are exceedingly rare. This magnificent ruby was a gift to the National Gem Collection and the people of the United States from Dr. Peter Buck, in memory of his loving wife, Carmen Lúcia Buck, who was born in Brazil and became a U.S. citizen. Her love for the United States, devotion to children, and appreciation for fine jewelry inspired the gift of this ruby for the children and families of the American People to enjoy.
